Update: Tubed is back with proper interchange times, smarter scoring, and out-of-station interchanges

Last week I posted about Tubed — the daily Tube puzzle where you build the fastest route between two stations and get scored against the optimal. A lot of you played it and gave some great feedback!

I've since gone back and rebuilt big chunks of it. Headline changes:

Interchange times are much improved: Every line-change at every station now uses real walking times.

Bank ↔ Monument is a proper cross-walk: You can change between them as part of your route and it's costed accurately per line pair, the way it actually works in real life.

Out-of-station interchanges added: You can now walk between nearby station pairs as part of your route, all timed accurately. Most pertinent ones added.

Massive network data audit: A bunch of branches were wrong.

Results screen shows the maths: Your route and the optimal route are both displayed leg-by-leg with explicit interchange times. No more "why is my score what it is" - you can see exactly where the time went.

Still a single HTML file, still no backend, still free. New puzzle every day at midnight, same one for everyone.

Still probably loads of bugs to squash let me know what you think!

Ever had that conversation when you meet someone in London on how they got to that place from their home? i.e. you must have taken the central line and then changed at Bank? Then they come back with something different?

Well I've been working on a little passion project based on this and figured here was a good place to share it.

It's called Tubed — every day you're given two Underground stations and have to build the fastest possible route between them. You pick your lines, make your changes, and your journey time gets scored against the optimal route.

A few things that make it interesting:

- You have to change lines at least once (there should never be a puzzle on the same line).

- Times are travel time only — no waiting factored in.

- Everyone in the world gets the same puzzle each day

- There are three hints if you get stuck

It's a single HTML file with no backend — all the network data and puzzle logic runs in your browser. Built it because I spend too much time on the Tube thinking about whether I'm actually taking the fastest route.

Would love to know what you think, especially if you spot any dodgy journey times — the data comes from TfL timetables but I'm sure there are edge cases.
